The Philippine serpent eagle (Spilornis holospilus) is an eagle found in the major islands of the Philippines. It is sometimes treated as a race of the crested serpent eagle (Spilornis cheela). This species is usually found in forest clearings, open woodlands, and sometimes in cultivated lands with scattered trees. It is endemic to the Philippines. The species is found on most part of the major islands, except for Palawan.
It is illegal to hunt, capture or possess Philippine serpent eagles under Philippine Law RA 9147. It has a length of 47 to 53 cm and a wingspan of 105 to 120 cm. This species is monotypic. The bird feeds on amphibians, reptiles and other live prey. Not much is known about its breeding habits. A female was collected with a single egg in its oviducts in April of 2020.
Its natural habitats are tropical moist lowland forest, montane forest, second growth and cultivated areas up to 2,500 meters above sea level. The IUCN has classified the species as being of Least Concern as it has a large range and it is common throughout its range and appears to adapt to second growth. Populations... Wikipedia →

Rare
Under 5% of wildlife watchers report a Philippine Serpent-Eagle sighting in Manila on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 132nd most-seen of the 191 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Philippine Serpent-Eagle in Manila on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Philippine Serpent-Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manila, in our data
Manila is the only city on Wallace's Line with enough records to rate Philippine Serpent-Eagle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Philippine Serpent-Eagle is recorded against all the birds logged in Manila (45 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
